Linkin Park member Joe Hahn continues to fill out the cast of his feature directorial debut “Mall,” as Gina Gershon (“Killer Joe”) and Peter Stormare (“Fargo”) have stepped in to replace Chelsea Handler and Eric Bogosian (the latter wrote the 2001 novel on which the indie film is based). Duo’s scheduling issues forced them to bow out of the pic, which has already started filming.James Frecheville (“Animal Kingdom”), Cameron Monaghan (“Shameless”), Gbenga Akinnagbe (“The Wire”), India Menuez (“Something in the Air”) and Mimi Rogers (“Austin Powers”) have also joined the ensemble, led by Vincent D’Onofrio. Bogosian’s debut novel follows five suburban strangers whose paths cross over the course of one hellish night at a shopping mall, where a drug-addled madman (Frecheville) goes on a shooting spree. Monaghan will play a teen stoner, while Menuez will play the object of his affection. Gershon will play a randy housewife who catches the eye of a voyeuristic businessman (D’Onofrio). Akinnagbe will play the mall security guard tasked with stopping the shooter, whose mother and former boss will be played by Rogers and Stormare, respectively. D’Onofrio is producing “Mall” with Sam Maydew, whose company the Collective reps D’Onofrio, Stormare, Rogers, rising thesp Menuez and Linkin Park. D’Onofrio also adapted the script with Joe Vinciguerra and Sam Bisbee. Epic Pictures will be handling foreign sales at Cannes, and they’ll have an additional selling point as Linkin Park has agreed to handle the soundtrack for the violent film, which will be exec produced by Bill Boyd and Rob Cavallo, chairman of Warner Bros. Records. Cavallo is responsible for some of the bestselling soundtracks of all time, and the “Mall” soundtrack will fall under Linkin Park’s record deal with Warners.

Frecheville is repped by UTA, the Schiff Co. and attorney Harris Hartman. Monaghan is repped by Gersh, KLWGN Entertainment and attorney Chad Christopher.
